During the analysis performed using HPLC-ELSD and GC-FID measurement, we attempted to elucidate the nature of the unidentified impurity by comparing the position of the peak that was observed in the measurement of the liposomal formulation of azelaic acid and the peak of azelaic acid that was present in the reaction mixture that was treated with ethyl alcohol in the presence of sulphuric acid.
During our analytical tests, we identified a previously unknown impurity of a liposomal preparation of azelaic acid that appeared in the liposomal formulation of azelaic acid during preliminary stability studies.
Chromatograms 1B and 1C are from a liposomal formulation of azelaic acid with an active ingredient (LA) and the azelaic acid liposomal formulation without substance (L), respectively.
The difference in acquisition costs of denosumab and zoledronic acid has become much greater since a generic formulation of zoledronic acid was approved by the FDA in 2013.
This finding led to the conclusion that the unknown impurity is formed via the reaction of azelaic acid with one of the excipients of the liposomal formulation of azelaic acid.
During the research and development of a new liposomal formulation of azelaic acid, we developed a method for determining the contamination of azelaic acid using HPLC-ELSD.
The following samples were tested: a liposomal formulation of azelaic acid prepared without active substance (placebo, L), a liposomal formulation of azelaic acid with active substance (LA) and a reference sample of AA.
Additionally, comparison of the mass spectra of the peak with a retention time of 8.0 min that is derived from a mixture of esters of azelaic acid (AA-Et-Sil) and the test sample of the liposomal formulation of azelaic acid that was stored for 12 months (LA-Et-Sil-2) confirms that the two peaks are derived from the same compound, in accordance with the data shown in Fig. 7.
